The circumference of a circle is the length that the circle would occupy if it were opened and laid flat on a surface as a straight line. For this reason, when calculating the distance travelled in circular motion, the circumference is used. The cirumference is calculated using: C = 2 pi radius
The circumference of a circle is the distance around it, calculated using the formula C = 2 π r . This formula shows that the circumference is directly related to the radius of the circle. Understanding this concept is important for various applications in mathematics and science.
